The term beams is used in this chapter as a generic term referring to all one‐dimensional parts that may be used in a structure. These include stiffeners, stringers, and panel breakers. There are many cross‐sectional shapes that are used in practice. Of those, the ones used most frequently are L or angle, C or channel, Z, T or blade, I, J and Hat or omega. For a composite beam, each member may have a different layup. This would result in different stiffnesses and strengths for each of the flanges and web and would allow more efficient usage of composite materials through tailoring. As beams tend to be used in stability‐critical situations, cross‐sections with high moments of inertia are preferred. In column buckling a beam under compression suddenly deflects perpendicular to its axis. Crippling is a stability failure where a flange of a stiffener locally buckles and then collapses.
